Respuesta :
x + y = 76
x = 4y - 9
4y - 9 + y = 76
5y = 65
y = 13
13 + x = 76
x = 63
Answer:
17 and 59
Step-by-step explanation:
Given: Larger of two numbers is nine less than four times the smaller number. The sum of two numbers is 76.
To find: Both the numbers
Solution:
Let the smaller number be x and the larger number be y.
It is given that the sum of the numbers is 76.
So, [tex]x+y=76[/tex]
Also, the larger number is 9 less than 4 times the smaller number. So, we have [tex]y=4x-9[/tex]
On substituting [tex]y=4x-9[/tex] in [tex]x+y=76[/tex] we get
[tex]x+4x-9=76[/tex]
[tex]5x-9=76[/tex]
[tex]5x=76+9[/tex]
[tex]5x=85[/tex]
[tex]x=\frac{85}{5}[/tex]
[tex]x=17[/tex]
So, the smaller number is 17
larger number is [tex]4(17)-9=59[/tex]
Hence, the smaller number is 17 and the larger number is 59.
